Effect of Heat Treatment of Microporous Glass on Its Structural and Electrosurface Characteristics

The structural characteristics, electrical conductivity, counterion transport numbers, and electrokinetic potential of microporous glass subjected to additional heat treatment at 750°С (MIP-750) in 0.1–0.0001 M NaCl solutions have been studied. The results obtained were compared with the properties of micro- and macroporous glasses prepared by the standard methods. It was found that with an increase in the pore size in the series MIP < MIP-750 < MAP, the absolute values of the electrokinetic potential increase.
